Question

Tolong jawab pake caranya ya kak plizz

Answer 1

10. Terigu : gula : tepung
7 : 4 : 5
280 : 160 : 200
gula = 160 x 6 = 960 (B)
* 280:7 = 40
40 x 4 = 160
40 x 5 = 20/
11. 5 5/8 gross - 3,5 lusin + 8 buah
= 45/8 . 144 - 3,5 . 12 + 8 buah
= 810 - 42 + 8 = 776 (C)
* 1 gross = 144 buah
1 lusin = 12 buah
Itu dulu ya ^_^

Answer 2

9) (10 - 2 × 1 2/5) ÷ 3/5 m
= (10 - 14/5) ÷ 3/5
= 36/5 ÷ 3/5
= 36/5 × 5/3
= 180/15 = 12(C)

12) 4,72t - (50×25000g+4,8kw+72+65)
= 4720 - (1250+480+72+65)
= 4720 - 1867
= 2853(B)

13) (543+45,2dm+6,4m) - 15,75m
= (543+452+640) - 1575
= 1635 - 1575
= 60(D)

14) 07 jam 15 menit 00 detik
-----01 jam 42 menit 43 detik
——————————————— +
-----08 jam 57 menit 43 detik
-----02 jam 18 menit 17 detik
——————————————— +
-----11 jam 25 menit 00 detik(D)

15) (2×0,605m³-20×12,5L) ÷ 7500³
= (1210000³-250000) ÷ 7500³
= 960000³ ÷ 7500³
= 128(A)
